FRAME FOR LONG MACHINES.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed January 25. 1907. erial No. 353,959.

' ging or deflection of the frame, or any part thereof, in any direction is prevented. So also must the connecting means have the same coeflicient of linear expansion as the needle bars, etc., so that they will expand and contract at the same ratio as the needlebars, etc., as otherwise the delicate operative mechanism would be thrown out of adjustment by variations in temperature.

By my invention the above objects are attained and novel means are provided for so connecting the standards with each other,

that the connecting means may be readily fitted in position, and that they will effect the desired alinement and stability to a superior extent.

In the accompanying drawings: Figure 1 is a front elevation of a machine frame embodying my invention; Fig. 2 a vertical transverse section on line 22, Fig. 1; Fig. 3 a detail of the rear connecting rods and boxes; Fig. 4 a perspective view of one of the front boxes, and Fig. 5 a similar view of one of the rear boxes.

A series of standards 10 constituting part of the machine frame, are set up at suitable distances apart and in parallelism with each other. These standards carry the shafting 11, and various other parts of the machine, such for instance as the needle-b ars in straight knitting machines. Each standard 10 is provided at its rear with an integral flanged plate 12, and at its front with a similar plate 13. To plate 12 is secured a box 14 by means of screws 15 that pass through the plate and engage tapped holes 16 in the top of the box. When these screws are tightened up, the box will be drawn against the plate with its top between the flanges thereof, so as to be securely held in position. Box 14 is slotted transversely to form two arms 17,

alined horizontal bores 19 and similar lower bores 20, which are vertically below bores 19. Bores 19, 20 are adapted for the reception of upper and lower braces 21, 22, respectively, which are of such a length, that they will connect all the standards 10 of the machine.

Each brace is secured to the box by means of a clamp screw 23 and a pin 24, the latter entering a transverse hole in the brace. Braces 21, 22 are composed of steel, this being the same metal out of which the needlebar and shafts 11 are constructed, so as to insure equal expansion and contraction under varying temperatures.

The front box 25 corresponds in all respects to rear box 14, excepting that its perforations 26, 27 are arranged sidewise of each other, the drawing showing the lower perforation to be placed diagonally from the upper perforation. This peculiar construction is selected with a view of shaping box 25 in conformity with the available space of standards 10, the point however being that the braces 28, 29, carried by the box, are placed sidewise of each other.

With the machine frame constructed as described, the boxes 14 with their braces 21, 22 will prevent sagging of the frame in a vertical direction, while the boxes 25 with their braces 28, 29 will prevent warping or deflection in a horizontal direction. In this way the stability of the frame against displacement in any direction is insured.

In assembling the parts, the boxes are first slipped over their braces and are then attached to the standards 10 by the screws 15. The standards, together with the boxes, are then shifted into their proper position, during which operation they will be held in parallelism with each other by means of the braces 21, 22, 28, 29. clamped to the boxes by screws 23, and are finally locked in position by the pins 24.

It will be seen that by my invention, ready means are provided for reliably truing the standards and preventing any deflection of the frame. Furthermore, the braces that connect the standards may be attached in a simple manner and in a direction at right angles to their axis, so that the machine may occupy the entire length of the shop. I

I claim:

1. A device of the character described, comprising a series of parallel standards,

Such braces are then shafts journaled therein and extending at right angles thereto, perforated boxes removably secured to the standards, and a plurality of braces secured to the boxes, the shafts and braces having the same coefficient of linear expansion, substantially as specified.

2. A device of the character described, comprising a series of spaced parallel standards, shafts j ournaled therein and extending at right angles thereto, a first and a second set of boxes removably attached to the standards, a first set of braces arranged side- Wise of each other and secured in the first set of boxes, and a second set of braces arranged vertically below each other and secured in the second set of boxes, the shafts and the braces having the same coefiicient of linear expansion, substantially as specified.

3. A device of the character described, comprising a series of spaced parallel standards, shafts journaled therein and extending at right angles thereto, a first set of boxes removably secured to the standards and having a pair of perforations arranged sideWise of each other, a second set of boxes also removably secured to the standards and having a pair of perforations arranged vertically below each other, a first set of steel WOLFGANG D.
